Keep the graphics to a minimum, make sure to name the page "sitemap," and don't make it the only way users can navigate, Spires says. It's also important
to submit the sitemap to the engines, as the links it contains will help their crawlers index all of the other pages on your site.
Be sure to include a clear and visible link back to your site's homepage on the sitemap -- preferably via your company's logo. And also don't forget to keep the sitemap link in the same place on each page.
